I have to agree with the OP. I sometimes carry a small motorcycle (1972 Yamaha AT2 125 Enduro) on a rack on the back of my RV. Last year, it was tied down a bit close to the RV and the handlebar grip rubbed on the back of the RV, leaving a black scuff. Nothing seemed to touch it, not even a brillo type scrubbie with Bar Keeper's Friend. On a lark, I grabbed a Mr Clean Magic Eraser, wet it, and rubbed. The scuff immediately came off, with very little elbow grease and without any damage whatsoever on the surface of the RV. I subsequently went all the way around my rig, touching up small stains and scuffs here and there. Fantastic! I put a couple in my storage compartment for future use!
